It’s floating, so it’s density must be less than 1 g/mL.

How can this be?

The Titanic is a hollow vessel full of air!

Slide 29

After HMS Titanic struck the iceberg, she started to fill with water.

What happened to her density?

As she took on more and more water, her density got closer and closer to 1 g/mL.

The denser the ship became, the lower she settled into the water.

Slide 30

What is the density of the Titanic resting on the ocean floor?

Must be greater than 1 g/mL, as her steel hull is full of water instead of air.

Slide 31

Where is the most dense object?

Where is the least dense object?

Slide 32

We don’t actually count g’s to find the mass of objects. How would you find the mass of a rock?

Use a balance scale.

In real life, how would you find the volume of a rock?

Use a graduated cylinder and see how much water the rock displaces.
